The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Complimentary light meal would be appreciated. But great flight crew service on all legs

The food was terrible this time. Otherwise pleasant, quiet, on-time.

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

More space for economy, and the bathroom size is only for people with size XS

Well, true to American Airlines, both of my flights were delayed. But it’s a good thing that American is so consistently incompetent because if the first flight was delayed in the second flight was on time then I might’ve had a problem..

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

The entertainment package was vast and the selections were very current. Keep updating it was great.

The seat was so hard my tailbone was aching The crew was kind of a b**** because I made a joke that I didn't care if they close the door I total c*** when she was trying to f****** act like she was mad at me because I said that The flight was bumpy. Sure you didnt have control over that.

Cramped seats. FAA should make airlines have more legroom, for even short people complain

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

We were bumped out of bulkhead seats we purchased a year ago. We were moved to row 5 and the folks in row 4 fully reclined making it difficult to get out to use the restroom. The seat have too little padding making them uncomfortable 3 hours into the flight. The movies did not offer closed captioning and the earbuds were poor so the entertainment was mostly unusable. The food was just passable. I would not fly Iberia/level again. Iberia also bumped us off our direct return flight so I would say the whole experience with this airline is poor.

Not bad but they lost 2 of my bags when I got to Florence

Couldn’t get boarding passes online, delayed an hour, and smallest amount of space on board I’ve ever encountered for such a long flight.

The crew were friendly and helpful. Iberia lost our luggage on arrival, Friday and we didn't get it until Sunday at 10:00 p.m. local Malaga time. I also paid $382.80 for seat assignments but two out out of the four were not together. Iberia mentioned that it was because the plane was delayed in Madrid before our flight began in LAX. They should compensate us half of my payment.

BEWARE!!! Iberia changes your seats at random. I paid for a window seat and they changed it to one in the middle aisle resting against the bathroom- can’t lean back + hear every flush. This on a 11 hour flight.. There were families that were broken up with separate seats all over the plane. Lots of upset passengers showing their seat confirmation to the besieged and helpless airline steward. Also, the gluten free meal was tasteless.

Flight delayed Service could be better Iberia staff are not really friendly

They cancelled the flight)(they said bad weather but many other flights took off) and made us wait 5 hours in line to figure out what to do. We ended up making a new flight the next day on another airlines...I hope they honor giving us our money back

We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude

Flight from Madrid to Dakar had no onboard entertainment for a business class. Not even a single screen . That was disappointing. The WiFi only worked for the first 45 mins of the flight.

No WIFI for the flight When told the breakfast item was cheese and tomato, did not mention sun dried tomotoes - totally different flavor and not what I wanted. Flyer for items for sale but none were offered.

TV wasn’t working, flight attendants never came when turning on the light, luggage was delayed and when delivered it was broken. No suitcase for the rest of our 2 week trip with no response when claimed filed

Definitely get premium economy on a flight this long if you can. Your legs and while body will thank you.

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

The food could be better, more snacks. And have some plugs to chargue the phone.

Second time I took this flight, and they lost my luggage both times. Waiting for my suitcase now, last time it took two days to get it back.

Used to love Lufthansa, but Rowe are too close together in Economy and passengers are allowed to recline their seats so far back it is impossible for those behind them to even reach for carry-on essentials during flight - except for meal service when flight attendants ask for seat backs to be raised, we can’t sleep on planes so this flight was most uncomfortable ever!

There were several delays in boarding. Then our group wasn’t called. Good thing we went up to the counter to see what was going on. We boarded next and last. I felt sorry for the staff but that was our third flight to get to our destination and we were tired.

The food could have been better. Had a wide range of entertainment to choose from.

I was traveling with a young child and the flight attendants were rude and unhelpful when simple requests were made like an early cracker or cookie to help distract him while everyone else was boarding. Also, my wife received dirty looks from an attendant when she asked if she could get by while holding our crying infant. They made us feel like a burden instead of a paying customer. The food was really sub par, especially the breakfast sandwich; cold, soggy veggie sandwich with no flavor (zero seasoning or vinegar or oil) and as mentioned the bread was cold and soggy wet. Also, there seemed to be something wrong with one of the bathroom’s ventilation, the smell was terrible throughout the entire flight. In the past Lufthansa had a good reputation for customer service, they are actively destroying it with how they currently treat passengers. If our return flight is as bad we will never fly Lufthansa again.

Dear Lufthansa, thank you for the excellent flight. We arrived early which really helped us with our connection. Crew was so nice!

A/C temp. was way too cold during the flight.

Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.

I was booked in Premium Economy and never given a chance to choose to purchase my own seat. Ended up with a middle seat, which was very difficult for me. The airline then left my bag in London so when I arrived in Instanbul it was not there. They delivered it to me the next day but many valuable items had been stolen. I've been flying with BA for years and this was the first time I had such a bizarre and bad experience with them.

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

Awful it always is unfortunately is the only way to fly direct to london

I’ll fly with any other airline. Besides all the fees and not being able to change a flight even to a later flight without paying £150 charge. Or that the last flight the WiFi didn’t work, the food was so bad, and ran out of options. Seat didn’t recline. And the headset jack didn’t work. This isn’t my first flight with them, and on every flight there is always something wrong that makes the long 10 hours feel like an eternity. Never flying them again.

Horrible. Never again. Wouldn’t let us use the lounge. We had to pay for another lounge to have access.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

Busy flight and less room to rest on overnight flight.
